An Investigation of Solids
First grade got their first taste of chemistry during their unit on Solids, Liquids and Gases. Through hands on explorations and group discussions, we learned about the properties of solids. Many people think that solids need to be hard but that's not true. Pillows, feathers, and yarn are all types of solids even though they are very soft and flexible. Solids are solids because they keep their shape no matter what kind of container they are in (unlike liquids and gases). A shell will still be shaped like a shell even if you put it in a square box; a cotton ball will still look like a cotton ball whether it is in your hand or in a cup. Although a common property of all solids is this definite shape, other properties (like hardness, color, texture, size, and shape) can differ greatly. When exploring these properties, the first grade made sculptures using only solid objects.
